Description
Die Erfindung betrifft das Gebiet der Lithium-Ionen Batterien und insbesondere die elektrische Verbindung zwischen den Elektroden von Lithium-Ionen-Batteriezellen und ein Verfahren zur Herstellung der elektrischen Verbindung.The invention relates to the field of lithium-ion batteries, and more particularly to the electrical connection between the electrodes of lithium-ion battery cells and to a method of making the electrical connection.
Die Erfindung ist anwendbar beispielsweise bei der Herstellung und bei der Verwendung von Lithium-Ionen-Batterien für Kraftfahrzeuge.The invention is applicable, for example, in the manufacture and use of lithium-ion batteries for motor vehicles.
Die Notwendigkeit des Einsatzes von Kupfer und Aluminium für die Elektroden der Lithium-Ionen-Batterien bedingt die Auseinandersetzung mit den physikalischen und chemischen Eigenschaften dieser Metalle an sich und den Effekten bei ihrer metallischen Berührung.The necessity of using copper and aluminum for the electrodes of lithium-ion batteries necessitates an examination of the physical and chemical properties of these metals per se and the effects of their metallic contact.
Besonders die negativen Eigenschaften von Aluminium, unter Druck zu fließen und an der Luft eine elektrisch nicht leitende Oxidschicht zu bilden, sind zu beachten. Die zwischen Kupfer und Aluminium besonders hohe Spannungsdifferenz in der elektrochemischen Spannungsreihe erfordert besondere Maßnahmen, um eine Zerstörung der Aluminiumelektrode zu vermeiden.In particular, the negative properties of aluminum to flow under pressure and form an electrically non-conductive oxide layer in the air, are to be noted. The particularly high voltage difference between copper and aluminum in the electrochemical series requires special measures to prevent destruction of the aluminum electrode.
Es sind schon verschiedene Vorschläge in dieser Richtung bekannt wie die Plattierung einer Verbindungslasche aus Aluminium mit Kupfer und die Entfernung der Kupferschicht an der Verbindungsstelle. Diese Maßnahmen beseitigen jedoch die Gefahr einer elektrolytischen Kontaktkorrosion nicht vollständig.Various proposals have already been made in this direction, such as the plating of an aluminum connection plate with copper and the removal of the copper layer at the connection point. However, these measures do not completely eliminate the risk of electrolytic contact corrosion.
Aufgabe der Erfindung ist es, den negativen Eigenschaften von Aluminium durch geeignete Maßnahmen entgegen zu wirken, das Auftreten einer elektrolytischen Kontaktkorrosion zu verhindern und einen langzeitstabilen niedrigen Übergangswiderstand an der Verbindungsstelle zu gewährleisten.The object of the invention is to counteract the negative properties of aluminum by suitable measures, to prevent the occurrence of electrolytic contact corrosion and to ensure a long-term stable low contact resistance at the connection point.
Erfindungsgemäß wird diese Aufgabe gelöst durch die Merkmale in den Ansprüchen 1 und 8. Zweckmäßige Ausgestaltungen der Erfindung sind in den Unteransprüchen enthalten.According to the invention, this object is achieved by the features in
Die vorteilhaften Wirkungen der Erfindung, insbesondere der niedrige Übergangswiderstand an der Verbindungsstelle, resultiert daraus, das die wahre Kontaktfläche der verbundenen Elemente, die im mikroskopischen Bereich durch eine Vielzahl punktförmiger Kontakte gebildet wird, durch Einlagerung von mikroskopisch kleinen Körnern aus metallischen oder nichtmetallischen Stoffen vergrößert wird, indem diese Körner in die Metalloberfläche eindringen, Aufwertungen bewirken und so die wahre Kontaktfläche vergrößern. Werden die Körner in eine pastöse Substanz eingelagert, z. B. ein Calcium-Lithium-Seifenfett, so erfolgt das Eindringen der Körner in die Metalloberfläche unter Luftabschluss und bei Aluminium wird eine erneute Oxydation der eben entstandenen metallischen Kontakte vermieden.The advantageous effects of the invention, in particular the low contact resistance at the junction, results from the fact that the true contact area of the connected elements, formed microscopically by a multiplicity of punctiform contacts, is increased by incorporation of microscopic grains of metallic or non-metallic materials By penetrating these grains into the metal surface, enhancing them and thus increasing the true contact area. If the grains are stored in a pasty substance, for. As a calcium lithium soap grease, the penetration of the grains in the metal surface under exclusion of air and aluminum is a re-oxidation of the newly formed metallic contacts is avoided.
Das kontaktverbessernde Mittel ist somit ein Gemisch aus Calcium-Lithium-Seifenfett und metallischen und/oder nichtmetallischen Partikeln, wobei die nichtmetallischen Partikel vorzugsweise aus Siliziumdioxid und die metallischen Partikel vorzugsweise aus einem Zink-Metallpulver bestehen. Das pastöse kontaktverbessernde Mittel hat eine Temperaturbeständigkeit von minus 40°C bis plus 130°C.The contact-improving agent is thus a mixture of calcium-lithium soap grease and metallic and / or non-metallic particles, wherein the non-metallic particles preferably of silicon dioxide and the metallic particles preferably consist of a zinc metal powder. The pasty contact improving agent has a temperature resistance of from minus 40 ° C to plus 130 ° C.
Zwischen den Elektroden der Batterie und den Kontaktelementen ist das kontaktverbessernde Mittel angeordnet.Between the electrodes of the battery and the contact elements, the contact improving agent is arranged.
Die Erfindung sieht weiter den Verschluss der Zellenverbindung durch eine Abdeckkappe vor, die eine Rastvorrichtung besitzt, welche an dem die Elektroden verbindenden Zellenverbinder befestigt wird.The invention further provides the closure of the cell connection by a cap which has a latching device which is attached to the cell connector connecting the electrodes.
Mit der Abdeckkappe kann die gesamte Verbindungsanordnung, also die als Kupferterminal und Aluminiumterminal ausgebildeten Elektroden, die metallischen Zellenverbinder mit den korrespondierenden Öffnungen sowie die Befestigungsmuttern gekapselt werden. Ebenso ist es jedoch auch möglich, mit einer kleineren oder einer aufgeteilten Abdeckkappe nur die als Aluminiumterminal ausgebildete Elektrode mit ihren zwei Befestigungsmuttern mit einem Teil des Zellenverbinders zu kapseln.With the cap, the entire connection arrangement, so designed as a copper terminal and aluminum terminal electrodes, the metallic cell connector with the corresponding openings and the fastening nuts are encapsulated. However, it is also possible to encapsulate with a smaller or a split cap only designed as an aluminum terminal electrode with its two fastening nuts with a part of the cell connector.
In der Abdeckkappe kann die luftundurchlässige, pastöse Substanz bereits eingelagert sein, so dass der Montageaufwand gering ist, wobei zwischen der Zellenoberseite und dem Zellenverbinder eine elastische Dichtung angeordnet ist, die eine Abdichtung gewährleistet.In the cap, the air-impermeable, pasty substance may already be stored, so that the assembly cost is low, with an elastic seal between the cell top and the cell connector is arranged, which ensures a seal.
Weiter sieht die Erfindung vor, dass der offene Boden der Abdeckkappe durch eine Folie abgeschlossen ist, die vor der Montage abgezogen oder während der Montage durchstoßen wird.Next, the invention provides that the open bottom of the cap is completed by a film that is removed before mounting or pierced during assembly.
Eine durch die erfindungsgemäße Lösung vorgesehene Füllung der Abdeckkappe oder einer separaten Aufnahmekammer mit der pastösen Substanz bewirkt eine totale Kapselung oder Versiegelung, welche einen Ionentransport und damit eine elektrische Kontaktkorrosion dauerhaft verhindert.A proposed by the inventive solution filling the cap or a separate receiving chamber with the pasty substance causes a total encapsulation or sealing, which permanently prevents ion transport and thus electrical contact corrosion.
Die Erfindung soll nachstehend an Hand von zumindest teilweise in den Figuren dargestellten Ausführungsbeispielen näher erläutert werden.The invention will be explained in more detail below with reference to embodiments shown at least partially in the figures.
